Corneal crosslinking performed in keratoconus patients induced a considerable decrease in corneal sensitivity. This decrease was more intense at the first week after the procedure, with a progressive recovery up to 6 months.

We modified the technique of Melles and obtained a sheet of Descemet membrane and endothelium with minimal endothelial damage and with no remaining stroma observed. This simple technique can be used to obtain the endothelium-Descemet membrane complex in minutes. It may be useful for corneal endothelium transplantation.

Further research with a greater bigger sample is necessary to establish the relation of androgen levels in dry eye patients.
